Thisinvention relates toapparatus for con' trolling contamination." in boiler or heating systems, brought about by oil tubefailure in a heat exchanger or preheater; More particularly, the invention deals with a control conduit or device having electric"eye`means for automatically shutting ofi the-water supply to a` boiler in the event of contamination and provision of means.l of ,draining contaminated water in renewal of the*systemper-ation after appropriate repairs have been made:V

The novel features of the invention will be best understood from the following-description, when taken together with the Taccompanying drawing, in which certainembodiment's' of the invention are disclosed and, in which,` the separate parts are designatedby suitable reference characters in each ofthevewsandnn which:` i i y Fig; 1 isa diagrammatic view1 illustrating part of a control systemwhich we'employ. i

Fig.` 2s an enlargedsection'al view throughjthe control device, detached; and

Fig. 3 is a section on the line 3--3 of Fig. 2.

In Fig. l of the drawing, we have diagrammatically illustrated at I the boiler. At II is shown an oil preheater and at I2 and I3 are the oil circulating pipes for the heater. Connected with the lower portion of the preheater is a valve control drain I4 and a valve controlled condensate discharge I5, including a trap I6.

While the invention is applicable to various types and kinds of heating systems operated by oil burners, in Fig. 1 of the drawing, we have shown a system, wherein a valve control pipe I1 is coupled with the boiler II) above the water line Ill', so that steam can be utilized for heating the oil in the preheater II. Interposed in the pipe Il, preferably adjacent the preheater, is a contamination control conduit or device I8.

The device I8 is shown in sectional detail in Figs. 2 and 3 of the drawing, the device comprising a anged body I9 having an enlarged or bulged central portion 20, as will be apparent from a consideration of Fig. 3. The central portion of the body I9 has an upwardly extending housing 2I terminating at its upper end in an inturned ange 22, the housing opening through the bottom of the body I9 and this opening is closed by a cap 23. Extending through the cap 23 are circuit wires 24 which control a pilot light 25 constituting part of an electric eye mechanism. The dome portion 26 of the light seats upon a neoprene gasket 21 which abuts the flange 22.

Fixed to the light 25 is a nut portion 28 which operates in the threaded portion of the housing i 2 and' a. lock nut'V 29 engages the threads of the housing to secure the lightin the desired position. Extending downwardly into the body of the device is a flow direction vane or baffle 38 which closely envelopes the opposed sides of the housing 2 I note Fig; 3, but is widely spaced from one end of the housingto form a large opening 3 I. The vane 30 opens 'into the other end of the body I9, as at 32.

It will thus beseen thatfin the event of leakage in the oil tubing; the oil will extend into the body I9 and create a discolored. condition over-the dome 28; which condition will cause the electric eye mechanism 33 to be actuated, thus through a suitable electric circuit incorporating one or morewell-kn'own controls, one of which is `shownfat 34 in Fig. 1` of 'thedr'awing the burner ofthe boiler willbe shutoff and a solenoid valve 35 will befactuated,l to drain the device and in some instances the system, through the drain pipe 36`extending from the solenoidvalve.

The' electric eye mechanism 33 is mounted upon the'top of the device I 8, through the medium of a mounting plate 31, which plate supports the magnifying lens 38 of the electric eye mechanism, the lens seating in a flange portion 39 at the top of the body I9. The lens 38 is in direct alinement with the light 25. The electric eye mechanism 33 is supported in a housing or cap 40, from which the circuit wires, as at 4I,

extend to the control 34, to which the Wires 24 also extend. Circuit wires 42 from the control 34 also extend to the solenoid 35' of the valve 35.`

The rest of the electrical system is not disclosed, as this system forms no direct part of the present invention.

It will appear from a consideration of Fig. 2 of the drawing that the solenoid valve 35 couples with one side of the valve body I9 through a pipe nipple 43.

It is immaterial whether the control conduit or device is operating on a iiuid or vapor system or, in fact, in any type or kind of fluid control where contamination or oli-color conditions prevail. The minute a clouded or oir-color condition exists in the body I9 and between the dome 26 of the light and the magnifying lens 38, the mechanism 33 will be actuated for the intended control purposes, the latter being governed by the apparatus and the electric system employed.

It will be noted that the device I3 is mounted in the pipe II or extensions thereof through the medium of quick detachable couplings 44 or 45, so that this control device can be readily cleaned, as and when contamination has prevailed and at the time that the necessary repair is being cared` 2,ece,14s k 1 2 3 for to eliminate the contaminating condition. This detachability of the control device I8 can be accomplished Without disturbing the remainder of the installation.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A device for use in pipe lines through which uids or vapors are adapted to pass, said device I having electric-eye means actuated upon the presence of discoloration in the uid or vaporV passed through the device, said electric-eye means comprising an electric-eye mechanism mounted on one wall of the device,V a light mounted in the opposed Walls of the device in alinement with said mechanism, said light being arranged in a housing portion extending into the device, and

' the rst named Wall of the device having a bafile' encircling the major portion of said housing.

2. A device for use in pipe lines through which fluids or vapors are adapted to pass, said device having electric-eye means actuated upon the presence of discoloration in the fluid r vapor passed through the device, said electric-eye means comprising an e1ectric-eye mechanism mounted on one wall of the device, a light mounted in the opposed walls of the device in alinement with said mechanism, said light being arranged in a housing portion extending into the device, the first named Wall of the device having a baffle encircling the major portion of said housing, and said light including a domed reflector sealed in the inner end of the housing.

3. A device for use in pipe lines through which fluids or vapors are adapted to pass, said device having electric-eye means actuated upon the presence of discoloration in the fluid or vapor passed through the device, said electric-eye means comprising an electric-eye mechanism mounted on one Wall of the device, a light mounted in the opposed walls of the device in alinement with said mechanism, said light being arranged in a housing portion extending into the device, the rst named wall of the device having a baille encircling the major portion of said housing, said light including a domed reilector sealed in the inner end of the housing, and a magnifying lens supported and sealed in the rstwall of the device between said light and said mechanism.
